What is Electric Field?
The force around the unit electrical charge particle is called an electrical field or electric field intensity. In other words, it is an area around the electric charge where another electric charge experiences the electric force. Electric field is a vector quantity, so it has both magnitude and direction. The symbol expresses the electric field, and it is measured in newton/coulomb.
Electric Field Formula
The formula for electric field can be given as,
=
where,
- is the electric force in Newton (N)
- q is charge in Coulomb (C)
Example: A force of 2 N is acting on the charge 6 μ C at any point. Determine the electric field intensity at that point.
Given,
- Force F = 2 N
- Charge q = 6 μC = 6 × 10-6 C
Electric field intensity formula is given by,
E = F / q
E= 2 N/6 × 10-6 C = 3.34 ×105 N/C
Thus, the electric field intensity is 3.34 ×105 N/C
Difference between Electric Field and Magnetic Field
Difference between an Electric Field and a Magnetic Field is Electric Field is the region around an electric charge in which another charge experiences the force of attraction and repulsion, whereas a magnetic field is the region around magnetic material in which it attracts or repels other magnetic materials.
Before learning the difference between an electric field and a magnetic field, let’s learn about what is electric field and what is magnetic field, their difference, and others in detail.
